阅读材料，完成下列要求。

材料：桑弘羊认为，一个强大的国家背后必须要有强大的经济实力支撑，所以朝廷必须掌握可靠的财政收入来源。他在改革中谏言汉武帝，指出“农商交易，以利本末”的国家宏观经济发展战略。在《盐铁论》中，桑弘羊说：“大汉辖内之天南地北，若无商贾所臻，则万物无所值也；商贾可累万金，皆于商道逐利而致；足民非井田一处，富国非农本一方。”公元前113年，桑弘羊向汉武帝谏言，提出彻底整顿货币秩序的一揽子建议。至此，五铢钱成为唯一合法的流通货币。币制改革的成功使朝廷的财政收入迅速增长，也巩固了西汉朝廷的政治统治。此外，军事开支有了充分保障，也鼓舞了对匈奴作战的汉军将士，取得对匈奴战事的连连胜利。

——摘编自吴兴彬《汉代传奇人物桑弘羊的经济思想发微》

    Today is Tom's birthday. After school he walks past the shop on the street corner. He looks into the window. That pair of trainers(运动鞋) is still there. He really wants to have them.

    He is very sad and walks away. He knows his mother can't buy him anything, because his mother has no money. The trainers are too expensive. He doesn't go home at once , because his mother can notice（注意）his worry. So he goes to the park and sits on the grass. Then he sees a boy in a wheelchair(轮椅). He finds that the boy moves(移动) the wheels with his hands. Tom looks at him carefully. The boy has no feet. He looks at his own feet. "It's much better（更好）to be without shoes than (比) without feet." he thinks. There is no reason for him to feel so sorry and sad. He smiles and thinks he is happy.
